である。In the figure, 21 and 22 are both optical disk substrates or substrates on which a flat information recording surface is preformed, and 23 is a spacer ring on the inner circumferential side of the substrate inserted to obtain the gap 20 between the two substrates. , 24 is a spacer ring inserted into the outer peripheral side of the substrate, and 25 is a through hole (spindle insertion hole) of the substrate.
It is.
従来、相互基板２１と２２の組立は、内外周に挿入のス
ペーサリング２３と２４により、該リングの表裏両面に
展着される接着剤層を介して貼合わせして組立られる。Conventionally, mutual substrates 21 and 22 are assembled by pasting spacer rings 23 and 24 inserted into the inner and outer peripheries via adhesive layers spread on both the front and back surfaces of the rings.

との接着強度が弱いなどディスク基板貼合に適用する適
切な接着剤を見いだすのは困難であった。However, a problem encountered in the above bonding is that the adhesive with strong adhesive force deteriorates the recording medium disposed in the inter-substrate sealed gap 20 due to the gas generated when the adhesive is cured. However, it has been difficult to find an adhesive suitable for bonding disk substrates that does not adversely affect the recording medium, but has weak adhesive strength with the substrate.
更に９組成の異なる複数の接着剤を使用する場合、接着
面が平坦なため各接着剤が混じり合ってそれぞれの接着
剤特性が活かしきれないとう問題があった。Furthermore, when using a plurality of adhesives having nine different compositions, there was a problem in that the adhesive surfaces were flat, so the adhesives were mixed together and the characteristics of each adhesive could not be fully utilized.
